Studies on natural product are aimed to establish medicinal values of plants by exploration of existing scientific knowledge, traditional uses and discovery of potential therapeutic agents. The phytochemicals are used as templates for lead optimization programs, which are intended to make safe and effective drugs1,2. A number of modern drugs like aspirin, digoxin, atropine, ephedrine, morphine, quinine, reserpine, tubocurarine and others are examples, which were originally discovered from the source of herbs3. The Nyctaginaceae is a relatively small family (there are 30 genus and 400 species) that occurs mainly in tropical and subtropical regions of the world4 with a few species in India, the Mascarene and Pacific Islands, and Africa5. It is commonly known as the Four-O’ Clock family, as most of the species have flowers that open in the late afternoon or early evening6. The family is best known to South Africans by the variety of Bougainvillas that are widely cultivated in gardens. Species of the introduced genus Mirabilis are erect, perennial herbs. The leaves are thin, opposite, ovate to ovate-cordate and the lower leaves have petioles, while the upper leaves are sessile. Flowers are subtended by a calyx-like involucre. The flowers are purple, red, yellow or white, open in the late afternoon and are fragrant at night. The anthocarp is black, hard and ribbed5. Mirabilis jalapa Linn. (M. jalapa Linn.) is a popular ornamental plant grown worldwide for the beauty of its flowers (which can be white, red, pink, purple, or multicolored) and their sweet fragrance7. It is using in almost all folklore remedies around the world for treating JBSO 2 (6), Nov - Dec 2014 a variety of conditions. The present article includes the detailed exploration of pharmacological and phytochemical properties of M. jalapa Linn. as an attempt to provide a direction for further research. Synonyms The synonyms of M. jalapa Linn. are; M. dichotoma Linn. (in Brazil), M. dichotoma Linn. and M. longiflora Linn. (in tropical America), M. lindheimeri Linn., and M. odorata Linn7. Vernacular Names Clavillia, four-o’clocks (in English); gulabas, sanjemallige (in Kannada); gulabbas (in Hindi and Marathi); krishnakeli, sandhykali (in Sanskrit); bathrachi, chandramalli (in Telagu); antinaralu, patharachi (in Tamil); don diego de noche (in Spanish); beauty of the night, belle de nuit (in French); vieruurbom (in Africa); shahelliilli (in Arabia); and tche kia hoa (in Chinese)7,8. Description and Distribution It was officially botanically recorded in 1753 although it already had long been distributed as an ornamental plant throughout the tropics of the world. There is some disagreement about where it came from originally: Mexico, Chile, or India. Today, clavillia is naturalized throughout the tropics of South America, Latin America, France and India. In Brazil the plant is known as clavillia, maravilha, or bonina; in Peru it is known as jalapa or maravilla. Hybrids of clavillia can be found in nurseries throughout the U.S. where they are sold as ornamental landscape plants7,8. The detailed taxonomy and Page 344 Ramesh B. Nidavani et al. Journal of Biological & Scientific Opinion · Volume 2 (6). 2014 morphology of M. jalapa Linn., are discussed in Table 1 and 2 respectively8,9. Traditional uses It has been extensively used in almost all folklore remedies around the world for treating a variety of conditions. It has been reported that indigenous Mexican people uses various decoctions and preparations of M. jalapa Linn. for the treatment of dysentery10,11. It is extensively using for muscular pain, diarrhea, and abdominal colic by people from other different countries12. Leaves are having sharp taste, maturant and generally used in inflammations. Leaves are also used to apply on boils, phlegmons, and whitlow as a maturant. Roots are used as aphrodisiac and good for syphilitic sores8. In China, has been used as traditional Chinese medicine and ethnic drug to treat diabetes13, constipation14, genitourinary system disorders, and injuries15. Apart from its medicinal uses, the flowers of M. jalapa Linn. are steeped in water to provide a crimson dye used in China for tinting cakes and jellies prepared from seaweed. A cosmetic powder is made in Japan from the powered seeds16. Toxicity Poisoning of children has been reported after consumption of roots, seeds or fruits of M. jalapa Linn17. Phytochemical Constituents Roots of M. jalapa Linn. contains alkaloids, glycosides, carbohydrates, and phytosterols by phytochemical analysis18. According to literatures, trigonelline is one of the components of M. jalapa Linn. root19. Trigonelline has been shown to reduce blood glucose concentrations in rats20 and in human21. The preliminary phytochemical investigation indicates the presence of flavonoids, tannic acid and phenolics in the plant22. The aerial parts of plants having beta-sitosterol, stigmasterol, ursolic acid, oleanolic acid and brassicasterol23,24. Pharmacological Activities In the recent years, the use of herbal products has been increasing in developing countries. Plants have always been an attractive source of drugs. On the other hand, intricate ways of molecular interactions and bioactivity mechanisms of the extracts or their bioactive constituents provide a challenge to the scientists25. The M. jalapa Linn. displays a wide range of pharmacological activities with correlate to mechanistic possibilities over respective disorders and overview of its pharmacological activities, has been presented in Table 3. Pharmaceutical Uses Reductant (reducing agent) for the production of gold nanoparticles Generally, nanoparticles are prepared by a variety of chemical methods which are not environmentally friendly. A rapid and convenient method to reductively prepare gold nanoparticles from auric chloride using aqueous extract of M. jalapa Linn. flowers. The flower extract acts as a reducing agent and encapsulating cage for the gold nanoparticles. The production of gold nanoparticles has been done by the controlled reduction of the Au3+ ion to Au0. The formation of gold nanoparticles has been established by FT-IR and UV-Vis spectroscopy. The study suggests that M. jalapa Linn. flowers can be a cheap source as a reductant for the production of gold nanoparticles37.

The agar ditch-diffusion method against E. coli, S. aureus, S. typhi, B. cereus, and K. pneumoniae The study reveal the immense potential of the plant for further research that aims at identifying the bioactive components responsible for the anti-oxidant activity and elucidating their tentative mechanisms of action22. Methanol extract shows potential antioxidant activity, further mechanistic study is required9. This activity is due to presence of flavonoids, polyphenols like phenolic compounds and tannins32. Water extract shows significant antioxidant activity and free radicalscavenging activity followed by methanol and dichloromethane extracts, due to high content of flavonoids and beta-Sitosterol identified for the first time by LC/MS and GC/MS, respectively33. These effects were not due to either Ach or His receptors blockage, IP3, cAMP, cGMP, Ca2+ release from intracellular storage, or protein kinase mediated contraction– relaxation mechanisms. The effects inducted by this extract may involve a serotoninergic mechanism, which, in turn, interacts with other adrenergic systems. Further studies are necessary to identify the active compounds to elucidate the mechanism of action34. Further investigations are required to identify the active principles in seeds of M. jalapa Linn 35.
